Chapter 1 INTRODUCTION
1.1 ABOUT THIS GUIDE
This guide provides technical information about Compaq Evo D300/D500 small form factor,
desktop, and configurable minitower personal computers and W4000 workstations that feature the
Intel Pentium 4 processor. This document describes in detail the system’s design and operation for
programmers, engineers, technicians, and system administrators, as well as end-users wanting
detailed information.
The chapters of this guide primarily describe the hardware and firmware elements and primarily
deal with the system board and the power supply assembly. The appendices contain general data
such as error codes and information about standard peripheral devices such as keyboards, graphics
cards, and communications adapters.
This guide can be used either as an online document or in hardcopy form.
1.1.1 ONLINE VIEWING
Online viewing allows for quick navigating and convenient searching through the document. A
color monitor will also allow the user to view the color shading used to highlight differential data.
A softcopy of the latest edition of this guide is available for downloading in .pdf file format at the
URL listed below:
http://www.compaq.com/support/techpubs/technical_reference_guides/index.html
Viewing the file requires a copy of Adobe Acrobat Reader available at no charge from Adobe
Systems, Inc. at the following URL:
http://www.adobe.com
When viewing with Adobe Acrobat Reader, click on the ( ) icon or "Bookmarks" tab to
display the navigation pane for quick access to particular places in the guide.
1.1.2 HARDCOPY
A hardcopy of this guide may be obtained by printing from the .pdf file. The document is
designed for printing in an 8 ½ x 11-inch format. Note that printing in black and white will lose
color shading properties.

1.2 ADDITIONAL INFORMATION SOURCES
For more information on components mentioned in this guide refer to the indicated
manufacturers’ documentation, which may be available at the following online sources:
♦ Compaq Computer Corporation: http://www.compaq.com
♦ Intel Corporation: http://www.intel.com
♦ Standard Microsystems Corporation: http://www.smsc.com
♦ Texas Instruments Inc.: http://www.ti.com
♦ USB user group: http://www.usb.org
1.3 MODEL NUMBERING CONVENTION
The model numbering convention for Compaq systems is as follows:
XXX/XNN/NN/N/NNNx
Removable storage: b = CD/CDRW, c = CD, d = DVD, r = CDRW, z = ZIP
Memory (in MB)
OS type: 2 = Windows 2000, 6 = Dual install, Windows NT 4.0 or 2000,
8 = Windows 98SE, P = Dual install Windows XP Pro/2000
Hard drive size (in GB)
Processor speed (2 digits in GHz)
Processor type: P = Pentium 4
Form factor: S = Small form factor, D = desktop, C = Convertible minitower
Model: D3 = Evo D300, D5 = Evo D500; W4 = Workstation 4000
1.4 SERIAL NUMBER
The unit’s serial number is located on a sticker placed on the exterior cabinet. The serial number
may also be read with the Compaq Diagnostics or Compaq Insight Manager utilities.

1.5 NOTATIONAL CONVENTIONS
The notational guidelines used in this guide are described in the following subsections.
1.5.1 VALUES
Hexadecimal values are indicated by a numerical or alpha-numerical value followed by the letter
“h.” Binary values are indicated by a value of ones and zeros followed by the letter “b.”
Numerical values that have no succeeding letter can be assumed to be decimal unless otherwise
stated.
1.5.2 RANGES
Ranges or limits for a parameter are shown using the following methods:
Example A: Bits <7..4> = bits 7, 6, 5, and 4.
Example B: IRQ3-7, 9 = IRQ signals 3 through 7, and IRQ signal 9
1.5.3 REGISTER NOTATION AND USAGE
This guide uses standard Intel naming conventions in discussing the microprocessor’s (CPU)
internal registers. Registers that are accessed through programmable I/O using an indexing
scheme are indicated using the following format:
03C5.17h
Index port
Data port
In the example above, register 03C5.17h is accessed by writing the index port value 17h to the
index address (03C4h), followed by a write to or a read from port 03C5h.
1.5.4 BIT NOTATION AND BYTE VALUES
Bit designations are labeled between brackets (i.e., “bit <0 >”). Binary values are shown with the
most significant bit (MSb) on the far left, least significant bit (LSb) at the far right. Byte values in
hexadecimal are also shown with the MSB on the left, LSB on the right.

2.3 MECHANICAL DESIGN
These systems are available in three form factors:
♦
Small Form Factor – a small-footprint desktop designed for environments where both
performance and space are critical issues.
♦
Desktop – a low-profile ATX-type desktop that satisfies standard expandability needs.
♦
Configurable Minitower – an ATX-type unit providing the most expandability and being
adaptable to desktop (horizontal) or floor-standing (vertical) placement.
The following subsections describe the mechanical (physical) aspects of the Compaq Evo models.
CAUTION: Voltages are present within the system unit whenever the unit is plugged
into a live AC outlet, regardless of the system's “Power On” condition. Always
!
disconnect the power cable from the power outlet and/or from the system unit
before handling the system unit in any way.
NOTE: The following information is intended primarily for identification purposes
only. Before servicing these systems refer to the applicable Maintenance And
Service Guide. Service personnel should review training materials also available on
these products.
